How It Works
Indexed universal life is permanent insurance with a cash value credited according to the performance of a market index, most often the S&P 500. You are not invested in the index. The carrier uses the index's movement as the input to a crediting formula, and that formula has both a ceiling and a floor.
Caps, Participation Rates, and Spreads
These three levers determine what you actually earn, and carriers can adjust them:
- Cap — the maximum credited in a period. With a 9% cap, an index gain of 22% credits 9%.
- Participation rate — the share of index movement used. At 70%, a 10% gain credits 7%.
- Spread — an amount subtracted first. With a 3% spread, a 10% gain credits 7%.
Most carriers guarantee only a minimum cap or participation rate, often far below the current one. A policy illustrated at today's cap can behave very differently if that cap is lowered a decade in.
Reading an Illustration Skeptically
IUL illustrations project decades of compounding from an assumed rate. Small changes to that assumption produce dramatically different outcomes, and no illustrated rate is a promise.
Ask for the guaranteed column — the one showing minimum crediting and maximum charges. That column is the contract's actual promise. Ask to see the policy illustrated at a rate two points below the default. If the policy only works when everything goes right, it is too fragile to hold your family's protection.
Being Straight About the Costs
IUL carries cost of insurance charges that rise with age, premium loads, administrative fees, and rider charges. These are deducted whether the index rises or falls. Underfund the policy, or let charges outrun credited interest, and the cash value erodes.
Our position: IUL is a legitimate product that is frequently oversold. It suits someone with a long horizon who will fund it consistently and review it annually. It does not suit someone who needs maximum death benefit today or who may stop funding it. If term serves you better, we will say so.
Common Questions
Am I invested in the stock market?
No. Your money is not in the index. The carrier credits interest based on a formula tied to index movement, subject to a cap and floor. You receive no dividends from index companies, which is a meaningful portion of long-run index return.
What does the 0% floor really protect?
It protects you from index-driven losses only. Policy charges — cost of insurance, administrative fees, rider costs — are deducted regardless. In a flat year you can credit 0% interest and still see cash value decline.
Can an IUL policy lapse?
Yes, and this is the risk to take seriously. If credited interest underperforms while cost of insurance rises with age, the policy can consume its own cash value and lapse — potentially creating a taxable event on outstanding loans. Annual reviews are not optional with this product.
